This Secret Santa app uses Twilio Programmable Voice and Airtable to facilitate managing participants and drawing names. The app is built using Twilio Functions, a serverless environment running Node.js. The code imports the Airtable package, creates functions for receiving calls, inserting data, and handling user input. The app prompts users to add their name or learn whose name they've drawn, depending on whether the organizer has already instructed the app to draw names. Users can then call in to find out who they are a Secret Santa to. The app uses Airtable's API to manage participant lists and drawing of names. After setting up the app, users can test it by calling their Twilio number and following the prompts. The app does not accommodate wish lists or other information but allows for expansion through customization.
